Young, resting neural stem cells have large protein clumps often associated with neurodegeneration. As stem cells age, the aggregates inhibit their ability to make new neurons, Stanford researchers say.

A Stanford researcher and his colleague got access to data showing the inner workings of an influential committee advising Medicare. They found that bias among its members has different effects from what critics claim.

Stanford scientists created an odd couple: a modified version of an immune-signaling protein and a coordinately modified receptor for this protein. The two bind only to each other, easing an advanced anti-cancer therapy’s side effects.
